Struct rp_pac::powman::regs::ExtTimeRef

#[repr(transparent)]
pub struct ExtTimeRef(pub u32);

Select a GPIO to use as a time reference, the source can be used to drive the low power clock at 32kHz, or to provide a 1ms tick to the timer, or provide a 1Hz tick to the timer. The tick selection is controlled by the POWMAN_TIMER register.

Tuple Fields

0: u32

Implementations

impl ExtTimeRef

pub const fn source_sel(&self) -> u8

0 -> gpio12 1 -> gpio20 2 -> gpio14 3 -> gpio22

pub fn set_source_sel(&mut self, val: u8)

0 -> gpio12 1 -> gpio20 2 -> gpio14 3 -> gpio22

pub const fn drive_lpck(&self) -> bool

Use the selected GPIO to drive the 32kHz low power clock, in place of LPOSC. This field must only be written when POWMAN_TIMER_RUN=0

pub fn set_drive_lpck(&mut self, val: bool)

Use the selected GPIO to drive the 32kHz low power clock, in place of LPOSC. This field must only be written when POWMAN_TIMER_RUN=0

Trait Implementations

impl Clone for ExtTimeRef

fn clone(&self) -> ExtTimeRef

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for ExtTimeRef

fn default() -> ExtTimeRef

Returns the “default value” for a type.

impl PartialEq for ExtTimeRef

fn eq(&self, other: &ExtTimeRef) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
